Existing two‐level binary logic and MOSFET (metal oxide semiconductor field effect transistor) technology have limitations. To overcome the limitations, three levels ternary logic with CNFET (carbon nanotube field effect transistor) technology is introduced. In this paper, the 1‐trit ternary multiplier is reconfigured for wide applications using CNFET Stanford model, for low and high die temperature. The proposed design is compared with two existing designs of the multiplier on the basis of power consumption, delay, requirements of the chip area, and other parameters. The proposed design uses a decoder that is a modified version of existing decoders. The role of the modified decoder is to convert ternary signals into binary form. Because of this conversion, analysis and implementation of the circuit become easier along with improvement in power consumption and delay with other parameters at low and high temperature.
